My sister is in the US for work, but because of the appalling services experienced by her, it hot of reviewing Uniconnect right in the moment!! We bought a Uniconnect Sim Card for US , obviously cz nobody wanted her to run to payphones / or buy those callng cards for calls. And being a pre-paid option it suited best for her. Turned out that it was poor judgement of the product. The credit was off after making one call that said i have got home safely! On recharging the number, not only was it difficult but a tedious job even on wifi, the site never seemed to load properly!! I guess we have made enough calls to the customer care, but they are equally useless! So now still in US she has bought a calling card to make calls!! Never suggesting Uniconnect to anyone ever!!
